A Gram-stain-negative, rod-shaped, motile, catalase-positive and cytochrome c oxidase-positive bacterial strain, designated AM20-91(T), was isolated from alpine forest soil. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain AM20-91(T) was related to the genus Lysobacter and had highest 16S rRNA gene sequence similarities to the type strains of Lysobacter novalis THG-PC7(T) (97.8 %), Luteimonas tolerans UM1(T) (97.7 %) and Lysobacter ximonensis XM415(T) (97.0 %). The strain contained ubiquinone 8 as the predominant respiratory quinone; its polar lipid profile contained phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and two unidentified aminophospholipids. The major cellular fatty acids (> 10 %) were iso-C-15 : 0, iso-C-11 : 0 3-OH and iso-C-11 : 0. The DNA G+C content was 63.35% (draft genome sequence). The combined results of phylogenetic, phenotypic, DNA-DNA relatedness and chemotaxonomic analyses demonstrated that strain AM20-91(T) represents a novel species of the genus Lysobacter, for which the name Lysobacter silvestris sp. nov. is proposed. The type strain is AM20-91(T) (=DSM 104734(T) =LMG 30011). In this study, it is also proposed that Luteimonas tolerans be reclassified as member of the genus Lysobacter.
